Figure 11. Four-parameter hyperparameter optimization was performed on the random forest model fitted to the plastic strain dataset. (A) Maximum depth; (B) Minimum samples segmentation; (C) Minimum sample leaf; (D) n_estimators; (E) Strength prediction graph of the best RF model under the optimal combination of hyperparameters. RF: Random forest; R²: the coefficient of determination; RMSE: root mean square error.
